His successor abandoned to the Assyrians most of the districts situated on the left bank of the Lower Zab between the Zagros mountains and the Tigris, and peace, which was speedily secured by a double marriage, remained unbroken for nearly half a century. Tukulti-ninip II. was fond of fighting; "he overthrew his adversaries and exposed their heads upon stakes," but, unlike his predecessor, he directed his efforts against Nairi and the northern and western tribes. We possess no details of his campaigns; we can only surmise that in six years, from 890 to 885,* he brought into subjection the valley of the Upper Tigris and the mountain provinces which separate it from the Assyrian plain. Having reached the source of the river, he carved, beside the image of Tiglath-pileser I., the following inscription, which may still be read upon the rock. "With the help of Assur, Shamash, and Ramman, the gods of his religion, he reached this spot. The lofty mountains he subjugated from the sun-rising to its down-setting; victorious, irresistible, he came hither, and like unto the lightning he crossed the raging rivers."** * The parts preserved of the Eponym canon begin their record in 893, about the end of the reign of Ramman-nirari IL The line which distinguishes the two reigns from one another is drawn between the name of the personage who corresponds to the year 890, and that of Tukulti-ninip who corresponds to the year 889: Tukulti-ninip II., therefore, begins his reign in 890, and his death is six years later, in 885. ** This inscription and its accompanying bas-relief are mentioned in the _Annals of Assur-nazir-pal_.
